Installation Preparation

Before installing the unit, perform the following procedures to ensure proper unit operation.

1.Verify the floor or foundation is level. Shim or repair as necessary.To ensure proper unit operation, install the unit level (zero tolerance) in both horizontal axis. Failure to level the unit properly can result in condensate management problems, such as standing water inside the unit. Standing water and wet surfaces inside units can result in microbial growth (mold) in the drain pan that may cause unpleasant odors and serious health-related indoor air quality problem.

2.Allow minimum recommended clearances for maintenance and routine service. See “Service Access” section on page 13.

3.Position the unit and skid assembly in its final location. If unit shipped split- apart, follow the procedure in the “Split-Apart Unit Assembly” section on page 16 before completing this step.Test lift the unit to determine exact unit balance and stability before hoisting it to the installation location. See Figure I-PC-7 and I-PC-8 on page 15 for typical rigging procedures, including cautions and proper uses of such equipment as fork lifts, spreader bars, and hooks.

4.Remove the skids from under the unit. See the “Rigging and Handling” section on page 14. Refer to the “Skid Removal” section on page 18. If you find internal damage, file a claim immediately to the delivering carrier.

5.Remove the protective shipping covers from the unit. Refer to the “Unit Protective Covers” section on page 35.

Note: Unit height and connection locations will change if external vibration isolators are used. The unit may be raised an additional 5-7/8inches with spring-type isolators.

Note: Unit height and connection locations will change if the unit is constructed to be split-a-part in the field. See unit submittal drawings for connection locations.

6.Electrical supply power must meet specific balance and voltage requirements, as described in the “Electrical Requirements” section on page 33.

7.Water-cooled units only (model SCWG): The installer must furnish and install a condenser main and standby water pump, cooling tower, pressure gauges and all components for the waterside piping. See the “Water Piping” section on page 30 for general waterside recommendations.

8.Air-cooled units only (model SCRG): These units require field-installation of a remote air-cooled condenser and refrigerant piping. See the “Refrigerant Piping” section on page 32 for general piping recommendations.
